Minimally Invasive Repair for Lateral Ventral Hernia: Tailored Approach from a Hernia Centre at a Tertiary Care Institution

Introduction: Lateral ventral hernia (LVH) is rare and can be primary or secondary. Surgical treatment of this rare hernia type is challenging due the anatomic location and technical challenges in placement and secure anchoring of mesh.

Method: Patient demographic data, intra-operative data and post-operative outcomes on all LVH repairs performed with endo-laparoscopic and robotic approach between 2016 to 2018 were reviewed and analysed.

Results: 22 LVH were repaired in 21 patients. 9 had primary hernia and 13 had secondary hernia. All patients underwent minimally invasive surgery (MIS) for hernia repair with no conversion to open surgery. Fascial defect closure and placement of mesh were performed in all cases. Different approaches were utilized: 9 hernia repaired with laparoscopic intra-peritoneal on-lay mesh technique with defect closure (IPOM +), 4 had laparoscopic trans-abdominal pre-peritoneal repair (TAPP), another 4 had extended totally extra-peritoneal repair (eTEP), 3 had robotic TAPP (rTAPP) and 2 repaired with trans-abdominal partial extra-peritoneal (TAPE) approach. 4 (19%) of the patients developed post-operative seroma which were managed conservatively. No other significant complication was noted, and no chronic pain or recurrence reported within a minimum follow-up of 12 months.

Conclusion: This case series gives a broad outline of possible MIS options available for LVH repair and recommendations for a tailored approach. The surgical technique needs to be individualized according to the size and anatomic location of the defect, other intra-operative findings and patient characteristics.
